(STMW) — A military veteran is accused of trying to bring a loaded handgun onto a plane at Midway Airport during the busy holiday travel weekend, the Sun-Times reports.

Josephine M. Coleman, 25, of Country Club Hills, is charged with boarding an aircraft with a weapon, and Cook County Judge James Brown ordered her held Sunday in lieu of $25,000.

Coleman was arrested Saturday, according to Chicago Police reports, after she placed a carry-on bag containing a Smith & Wesson handgun loaded with seven live rounds on a Transportation Security Administration X-ray machine.

She was allegedly on her way to Southwest Airlines flight No. 1404 bound for San Antonio.

Coleman said she didn’t know the gun was in the bag, police said.

“I’m in the military,” Coleman said, according to police. “And I have a FOID card.”

Coleman’s firearm owner’s ID card is valid, according to the police report.
